Frequently asked questions

Common questions about LMI PUMPS RPM from 3G Electric.

What is included in an LMI Pumps RPM pump head service kit?

An LMI Pumps RPM pump head service kit typically includes a diaphragm, check valves (ball and seat), seals, gaskets, and O-rings. The exact contents vary by kit part number (e.g., RPM-D58, RPM-917). These components are necessary to rebuild the pump head, restoring its ability to maintain accurate flow rates and prevent leaks. Each kit is designed for a specific LMI pump model or series, so it is important to verify compatibility using the manufacturer part number.

How do I select the correct LMI Pumps RPM kit for my pump?

To select the correct RPM kit, identify the manufacturer part number of your LMI pump head or the pump model number. The RPM kit part numbers (e.g., RPM-455, RPM-833) correspond to specific pump configurations. Cross-reference the pump's serial number or model plate with the LMI parts catalog. 3G Electric provides datasheets for each SKU that list compatible pump models. If you are unsure, contact 3G Electric's technical support with your pump details for assistance.

Are LMI Pumps RPM kits compatible with all LMI metering pump models?

No, LMI Pumps RPM kits are model-specific. Each kit is designed for a particular pump head design, flow range, and pressure rating. For example, RPM-352/358 is for specific pump models, while RPM-D18 is for another series. Using the wrong kit can lead to improper sealing or performance issues. Always verify compatibility using the manufacturer part number or consult the datasheet provided by 3G Electric.

What is the typical service interval for replacing an LMI Pumps RPM kit?

The service interval depends on operating conditions such as chemical type, temperature, pressure, and duty cycle. LMI recommends inspecting pump head components annually or after 3,000 hours of operation, whichever comes first. Signs of wear include reduced flow accuracy, leaks, or visible diaphragm damage. Replacing the RPM kit at these intervals helps maintain pump performance and prevent unplanned downtime.

Can I get technical support for LMI Pumps RPM kit installation from 3G Electric?

Yes, 3G Electric provides technical support to assist with part selection and installation guidance. While the kits include installation instructions, their team can help clarify compatibility questions or troubleshooting steps.
